I also have a Sansa Clip Plus so: can I connect it to the receiver? There is no Aux-input and in some webs I read that you can connect your DAP to the CD-input, it's this alright? Why? What's the difference with the others?
If I want to connect the PC, is the same?

I don't want to break the receiver or the Sansa/Pc jajaj.

Some advice/recommendation about the speakers? Do the speakers need any special requirements?
